Urban Hackers Turn Billboard into Merry-Go-Round

Billboards are ubiquitous sights in urban settings. As conduits for advertising, they are often viewed as eyesores and ignored by passersby. To reclaim the space of a spinning billboard in Prague, urban hackers Vojtěch Fröhlich, Ondřej Mladý, Jan Šimánek and Vladimír Turner turned the structure into a temporary merry-go-round late last year, creating a moment of escape within very public view.
